Colony in Space - Episode 3

Ho-hum. It's a shame that Pertwee's first adventure in Space is this. The colonists with their 70's hippie hairstyles and mustaches and beards are goofy. Interesting to see the Doctor in disguise, in an IMC uniform. Poor Jo gets chained to a bomb. I like the nice IMC fellow, Caldwell. I knew that Norton was no good, I suspected he was a plant. The clue should have been he was played by one of the Dalek voices. But then, the colony leader Ashe is played by the evil Tlotoxl from "The Aztecs". You never know. Still no sign of the Master. Instead we get a really poor cliffhanger, Jo being led into a cave by the Primitives.
